SBC Not Talking to PBX with Audit/Options Messages

Jump to solution

I have a Openscape Voice PBX and am using a NetVanta 3430 for the SBC. I have functionality calling inbound, however when calling out the PBX will not talk to the Adtran. It states it is not accessible. It is suppose to be sending an audit message to verify its alive before sending it calls, but I am guessing it is not allowing or sending the correct signal back.

Any ideas? I called support and put in a ticket, but I thought maybe someone knew what was up.

Thanks!!!

Robert,


Is your PBX using an OPTIONS message as the audit mechanism? AOS devices will not respond to OPTIONS messages unless the username in the Request-URI of the OPTIONS matches a valid sip-identity or user. If you are using OPTIONS, you would need to configure a voice user similar to the below in order for us to response with a 200 OK.

voice user 0000

  sip-identity Openscape T01

Where 0000 stands for any user that is not currently in use and will never be needed. The “Openscape" portion corresponds to the user in the Request-URI of the OPTIONS message. The "T01" portion must mach the SIP trunk that is receiving the OPTIONS keepalive. With this added, the device will respond to the OPTIONS message with a 200 OK instead of a 501 Not Implemented.


Thanks!

Rob

Would there be a command on the adtran to see this username on the adtran when it rejects it?

thanks!

"debug sip stack messages" will show you the SIP communication between your PBX and the ADTRAN. From that debug, you can look at the OPTIONS message from the PBX (assuming it is using OPTIONS) to determine what it is using for the user portion of the Request-URI.

Awesome Thanks!!! We got it working. We had to setup the register sip username and password.
